I have extensive experience with website updates and the Divi2 theme. It's one of the most widely used themes at the studio I work for. I currently work from home and have plenty of time I can dedicate to your project.
I would keep track of my hours on a spreadsheet and send them to you at the end of the month or as requested. I use Toggl to keep track of my exact hours worked.
Please feel free to contact me if you have any questions, or we can discuss your project needs in further detail.
